MARCIA BRADY TRADED SEX FOR COKE

Oh, my nose!

TV sweetheart Maureen McCormick traded sex for cocaine and wasted her young adulthood hooked on drugs, the “Marcia Brady” actress admits in a shocking tell-all book.

McCormick’s perpetually upbeat “Brady Bunch” character was the polar opposite of herself as she led an off-screen life of nonstop debauchery, according to her memoir, “Here’s the Story: Surviving Marcia Brady and Finding My True Voice,” which hits bookstores tomorrow.

“As a teenager, I had no idea that few people are everything they present to the outside world,” writes McCormick, now 52, who chronicles her romance with TV brother Barry “Greg Brady” Williams and dates with Michael Jackson and Steve Martin.

“Yet there I was, hiding the reality of my life behind the unreal perfection of Marcia Brady. No one suspected the fear that gnawed at me even as I lent my voice to the chorus of Bradys singing, ‘It’s a Sunshine Day.’ “

In her post-“Brady” days, McCormick says she spent her nights hitting wild Hollywood parties at the Playboy mansion and the home of Sammy Davis Jr.

She went off on cocaine binges, trading sexual favors for drugs, leading to unwanted pregnancies.

McCormick was 14 when she started her 1969-74 “Brady Bunch” run on ABC. She also had a brief stint on its short-lived spinoff, “The Brady Brides,” in 1981.

McCormick claims drugs hampered her acting career – and she even blew an interview with Steven Spielberg because she was high.

After a several stints in rehab and interventions by loved ones, McCormick is now not-so-ironically living an idyllic suburban life in Westlake Village, Calif., that bears an uncanny resemblance to her pretend “Brady” life.

“It’s like ‘Leave It to Beaver,’ ” McCormick told the Chicago Tribune earlier this month.

“Everyone knows everyone, everyone helps everyone . . . It’s the best. It’s like Andy and Mayberry.”

In her memoir, McCormick writes that she doesn’t regret a day of her “Brady” years, even if they now serve as a stark reminder of her out-of-control off-screen life.

“I’ll always be struck by how much a part of people’s lives Marcia is and always will be,” she writes. With Post Wire Services
